f-Referring tothe drawings, I have shown a stud including a head 1, neck 2 and a bass-3,3 secured-to the studscarrying fabrics byvthe usual rivet 5 and cooperatingfwith} a I socket secured to the socketscarrying fabric 6 by the attaching prongs 7 which penetrate the'socketecarrying fabric 6 and are clenched within the usual socket-securing cap 8 It will be understood that, while I have re? ferred to the socket and stud-carrying fabric, any suitable flexible materialf nay be use A 1 v I A The socket properi'includesthe casing 9 containing a spring 10 of the type present ing generally parallel resilient end portions or; jaws 11 for engagement with the neck-21 of the stud and resilient. reverse bends con nesting theseends.withanhintegral support 12 ad acent the periphery, of the casing 9,.

The socket also includes a casing closure plate 13 securedto the casing by, bending.

inwardly, a r i n of t e upstandin sln P 7501 of the casing s ill t in i 3 and15; 1 V

The attaching prongs are presented by the closure plate 13, which is supported by w upsta pr i c i n pre ed from theface of the socket, as illustrated,

therebyspacing the closure plate from the face of the casing so as not to interfere with the movement of the resilientparts of the also to support'the closure plate whenthe prong *Z-ar leneh dvinte engag ment w t the cap 8s The socket also presents a stud-receiving theneck2 of the stud. This aperture is ex--' a tended by two notches-16, 16 whichextend from, the aperture on a diametrical line parallel with the aws and provide alateral I lock againstseparatio'n of the fastener by a strain'exerted in the direction of either of thenotches- A The projections 14, 14 are located at the.

notches in the casing by either of the projec- 'tions before the closure plate is secured to thecasing, whereas, if the projections are located on the closure plate, the closure plate ust be positioned relative to the spring'andthe spring must be positioned in the casing without anything to keep in position during. assembly of: the socket proper. In my invention, however, asfillustrated, the spring may be placed in the casing and positioned the projections 14,

14, thus making it unnecessary to position the'closure plate relative to the spring or the casing.

ln secunng' the socket to theglove or I other flexible materiak one of the notches,

which are of less Width than the diameter of'the. neck 2 of the stud, should be positioned infthefjli-ne of strain or toward the adjacentedgerofthe material. Thus,when

stresses are" exerted in opposite directions upon the stud and socket -a portion of the neck 2 of the s-tudwill enter one of the notcheslti, to provide a lock I against-the separating Strain arising frorn the resolution of forces when the fastener-partsunder lateral stress as. disclosed in my United States Letters Patent No,;1,5,13,9e4, issued 7 I November 4, 1924.

IWhile I have shown and described a preferred embodiment of my invention, it'will be understood that changes involving oinission, substitution, alteration and reversal of I I parts, and even changes in the modeof Openprlll syas' s ated. 1' g -Y 3 a d I ation, maybe inade without departing from the scope of my. invention, which is best defined in the appended claims.

Claims: I I 1-, 1. A separable fastener comprising, in o bina iom a ud e s a e d a a ne k, a, cooperating s cketin luding ac s its ing presenting a stud-receiving aperture therethrough, a spring in said casing presenting stud-engaging portions intersecting said aperture a notch at one side of said aperture of less width than the diameterof the neck of the stud for receiving a portion of the neck of the stud to lockthe fastener when under lateral strain in the and the stud-receiving aperture.

2. A- separable fastener comprising, in combination, a stud having a head and a neck, a cooperating socket including a casing presenting a stud-receiving aperture therethrough, a spring in said casing presenting stud-engaging portions intersecting said aperture, a pair of diametrically opposed neck-rc'ceiving notches at the periphery of said aperture into one of which a portion of the neck of the stud may be received when the fastener is, under lateral strain in the direction of the notches and ail-upstanding projection pressed from said casing at the end of each notch, one of said projections positioning the neck-engaging portions of said spring relative to said notches. 1 v

3. A separable fastener comprising, in combination, a stud havinga head and a neck, a cooperating socket including a casing presenting a stud-receiving aperture therethrough, a neck-receiving notch at the periphery of said aperture into which only i I a portion of the neck of the stud maybe pulled when the fastener parts are under lateralstrain, a projection extendingfrom said casing at the end of said notch, a re turn bend spring in said casing provided with neck-engaging portions positioned relative to said notch by said projection and aclosure plate fitted within the casing and supported by saidprojection, the marginal flange of said casing being thrown inwardly over said'closure plate to secure said closure plate and casing together.

4HA separable fastener comprising, in combinatiom a stud having a head and a neck, a cooperating socket including a casing presenting a stud-receiving aperture therethrough, a pair of diametrically 0pposed notches at the periphery of said aperture, said notches being of such width that only a portion of the stud may enter when the fastener parts are under lateral stresses,

a spring of the return bend type located in said casing, a rpro ectlon extending from said casing at the end of each notch, one

of said projections positioning the neck-engaging portions of the spring relative to said notches and a closure plate presenting a plurality of prongs for attaching said cluding a casing containing a spring presenting generally parallel resilient neck-engaging portions, a stud-receiving aperture in said casing, notches provided at opposite sides of said aperture and located between said neck-engaging portions of the spring, each notch being of such width as to permit only a portion of the neck of the stud to en ter when the stud and socket are under lateral stresses, a closure plate presenting a plurality of attaching prongs for securing said casing to a flexible support and aprojection extending toward said closureplate from the outer end of each notch,said proj ections formed from the material struck out to provide said notches and said projections supporting said closure plate and position ing said resilient neck-engaging portions relative to said notches. I

6. A separable fastener socket including a casing presenting a studreceiving aperture therethrough having opposed notches in the wall surrounding the aperture, a spring in said casing presenting a pair of resilient neck-engaging jaws intersecting said aperture, said notches being located between the jaws of said spring and being of less width than the neck of a cooperating stud, thereby to receive only a portion of the neck of the stud when the fastener parts are subjected to lateral stresses, a closure plate secured to said casing and a plurality of projections pressed from the face of said casing at the outer ends of said notches for spacing said closure plate from said spring and for positioning the jaws of said spring relative to said aperture and said notches, said projections providing the only means for spacing said. closure plate relative to said casing.

7. A separable fastener socket'including a casing presenting a notched aperture therethrou'gh, the notch being of less Width than the diameter of the neck of a cooperating stud, thereby to receive only a portion of the neck of the stud when the fastener parts are subjected to lateral stresses, a spring in said casing presenting a pair of resilient neckcombination, a stud secured to a stud-carrying Inediunna cooperating socket secured to a socket-carrying medium, said socket providing a casing having a stud-receiving aperture, a spring located in said casing and presenting j aw, portions intersecting said aperture, a notch of less width than the diameter of the neck of the stud at that side 7 of said aperture adjacent the free edge of the socket-carrying medium to receive only a portion of the neck of a stud when the fastener parts are subjected to lateral stresses the neck of the stud into the notch and a pro-. jection formedv from the metal struck out to provide said notch, said projection position- '10 ing said spring jaws relative to said notch. In'testimony whereof, I have signed my name to this specification. I FRED S. CARR.
